WILLIAM WILDT, OF RICHMOND, VIRGINIA. l

ENGRAVERS Tool..

SPECIFICATION forming part of Letters Patent No. 297,213, dated April 22, 1884.

I Application led January 28, 1884. (No model.)

Zh all whom iv' may concern.-

Be it known that I, WILLIAM WILDT, a

Virginia, have invented certain new and useful Improvements in Engravers Tools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters or iigures Vof reference marked thereon, which form a part of this specification.

My invention relates to improvements in engravers tools, and more especially to that class whereby objects of small dimensions may be more conveniently held for the purpose of engraving the same.

The object of this invention is to provide a convenient adjustable tool in which are employed a stationary rest or table and a loop or arms for holding the object firmly on said table or rest, said parts being made detachable for the purpose of substituting a loop or arms or a rest, or both, of different form, to adapt the tool for use in holding articles of various configurations, as hereinafter more fully described, and as shown in the accompanying drawings, in which Figures l and 2 illustrate my improved tool by vertical front and side elevations, respectively. Figs. 3 and 4 illustrate the same by vertical sections taken at right angles to each other on a line with the vertical axis of the tool. Figs. 5 and 6 are detached isometrical views, showing one form of the interchangeable stationary support or table and adjustable retaining or holding device, respectively, for holding cylindrical objects, shown in Figs. l, 2,' 3, and 4. Fig. 7 is a like view, showing the like devices for holding spherical objects. Fig. 8 also shows by a detached isometric-al view still another form of said interchangeable devices. l

In these drawings, A indicates the stockhandle of the tool, which is formed of two parts or sections, A A, connected together in such manner as to rotate one upon the other. The part or section A of the stock or handle is slotted transversely, the slot a extending downward for a certain distance, and -the length thereof determines the extent of the vertical movement of the adjustable retaining or holding device where the tool consists of a stationary support or rest and a retaining or holding device adapted for adjustment relatively to and above said stationary support on a line with the longitudinal axis of the handle or stock of the tool.

Upon the upper end of the part A is detachably secured in any convenient manneras, for instance, by means of set-screws a-a thimble or sleeve, B'. This thimble, if desired, may be secured to the part A of the holder by screwing the same thereon, or by means of a bayonet or other interlocking joint, to adapt the same for ready removal and substitution of another, for purposes which will be presently described.

The thimble B is provided with a support or rest, B, corresponding to or nearly corresponding to the form of the object to be held by the tool, as shown in Fig. 1. The support or rest B is made in the form of a segment of a circle both longitudinally and in cross-section, as `shown in Fig. 4, the parts being` more especially adapted for cylindrical objects-such as rings-to afford means for more conveniently handling the object, aswell as to afford easy access to the interior periphery thereof. At its opposite ends the support or rest B is secured to the sleeve orthiinble B by means of arms b', and at said points said support or rest is provided with slotted guidebearings or lugs b.

It is obvious that, instead of forming or attaching the bearings b to the support B, these may be formed on or attached to the thimble B and perform the same function.

At or near the lower end of the part A of the stock or handle is formed an annular groove,

a2, for the reception of a split ring, D, by me'ans of which the two parts of said stock or handle are rotatably connected with each other.

VThe part A has also an axial perforation or passage, a3, extending from its lower end to the slotl a thereof.

The part A is provided at its upper end with a sleeve, C, secured thereto in any suit- IOO able manner,.to form a socket, a, as shown in Figs. 8 and 4, for the reception of the lower grooved end of the part A of the handle.

The sleeve C is secured by means of screws c within a suitable recess or countersink or bearing, E, provided with a central screw-threaded opening or passage, c. This bearing may be made in the form shown in Figs. 3 and 4, or it may be a simple plate or block of metal secured to the part A2 by means of two screws, and provided with a screw-threaded perforation registering` with the axial passages of both sections of the stock or handle..

G indicates a sleeve fitted to and arranged to slide vertically on the part A of the han dle between the sleeve or thimble B and an annular shoulder or offset, a, formed on the part A of the handle, the two limiting the extent of movement of the sleeve in either direction. The sleeveG has on its opposite sides a pin or stud, g, terminating in 'a button, g', and below the pins g, and in the same vertical planes, the sleeve is provided with a pin, g2. Centrally across the sleeve is attached a crossbar, h, that extends across the slot a and moves with the sleeve. To the center of the crossbar 7a is rigidly attached an actuating screwrod,H,that passes through the axial passage a3 and works in the screw-threaded bearing E of the section A` of the handle A, so that when either the part A or Al is rotated in one direction the sleeve G is moved upward on the section A,'and when rotated in a reverse direction said sleeve is moved downward on said section A of the handle or stock.

It is obvious that if the movable holding or retaining device of the tool is connected with the sleeve said part can be moved toward or from the stationary support or rest B. This movable holding or retaining device, which serves to hold the object on the support, may be rigidly secured to the sleeve G, in which case it is obvious that but one form of support and retaining device can be used, especiallyv if the thimble or sleeve B is permanently at tached to the part A of the stock or handle. Even in case said sleeve is removably secured to part A', as above set forth, it would be necessary, when it is desired to substitute one set of holding devices for another,to remove therewith the sleeve G and screw H. To avoid this I connect the movable part of said devices with the sleeve G in such manner that it may be readily detached therefrom and another one applied either in combination with the same stationary support or rest, or by removing both and substituting othersof the desired form.

As shown in Figs. l, 2, and 3, the adjustable holding device Fis designed for use, with the support B, for holding cylindrical objects, and more especially rings and like cylindrical objects, and is composed of a piece of spring metal bent into U shape, the segmental portion f of which has its inner face of segmental form in cross-section, or concave, thus forming a groove like the groove in the support or rest B, in which the ring or other like object is securely held.

The legs F of the holding device F are provided near their lower extremities with a hole, f2, for the reception of the pins g2, and above said holes with a slot, f', terminating at its upper end in a circular hole, forming a button-hole. In this manner, if it is desired to attach thepart F to the sleeve G,the.legs there of are passed through the slots in the guide bearings or lugs Z) of the stationary support or rest B, then over the buttons g of the pins g, and drawn upward until said pins lie in the end ofthe slots,when the ends of the legs will be in a position for the pins g2 to pass through the holes f2, thus securing the part F iirmly in place. To remove the said part F, the lower ends of the legs are lifted off the pins g2, and the said part F is then pushed down until the buttons y on pins g lie in the circular hole at the ends of the slots f', when the legs may be readily detached and drawn out of the bearing-lugs of the support or rest B. These pins not only serve to securely lock the part F to the sleeve G, but they also serve to hold said part against vertical movement when operated by the screw H.

It is obvious that if the pins g2 were not employed there would be a lost motion correspondiug with the length ofthe slot in the legs of part F, and if the pins g were dispensed with the said parts would be liable to become detached.

Any other method of attaching the legs of the part F to the sleeve G, so that they may be readily detached, may, however, be employed-as, for instance, a hollow interiorly screw-threaded stud, in conjunction with a button having a screw-threaded shank-may be employed, or other analogous fastening devices. The sleeve G may be dispensed with andthe legs F of the part F may be secured directly to the cross-bar lz..

It is obvious that by means of the described construction, in a very short time, either one or both parts B and F may be readily removed and corresponding parts of other form substituted--as, for instance, the devices shown in Fig. 7, whereby a spherical object may be conveniently held, or the devices shown in Fig. 8, whereby objects of other form may be securely connected with the stock or handle; or any other desired form of holding devices may be employed-forms which, from what has been said, will readily suggest themselves IOO IIO

to the engraver or manufacturer of such tools,

`according to the object or article to be held thereby, and an assortment of such devices may be provided for each stock or handle.

The operation of the tool will be readily understood from what has been said and by an inspection of the drawings, and further de-4 scription thereof is deemed superfluous.

Having now described my invention, I would have it understood that I do not desire to claim, broadly, an engravers tool of the class described, as I am aware that such tools are in use to which cylindrical objects or objects of other form may be secured; but

What I do claim is" l.
